Definitions

  • the present disclosure relates to irrigation devices. More particularly, the present disclosure relates to a width control mechanism for a sprinkler.
  • Irrigation devices such as sprinklers
  • fluid such as water
  • desired areas typically without user control.
  • owners/users of the irrigation devices to tend to other tasks while fluid is being provided to a desired area (e.g., a region of a lawn, a flower bed, etc.).
  • irrigation devices including, but not limited to: a pop-up sprinkler that is stored at or below a ground surface that selectively "pops-up" when in use to provide fluid; impact or impulse sprinklers that utilize fluid flow to drive rotation of the spray nozzle of the sprinkler; fixed spray sprinklers that provide a fixed stream of fluid (e.g., no rotation or other movement); oscillating sprinklers that provide a stream of fluid and oscillate about an axis of rotation; and various other types of irrigation devices.
  • a previously known irrigation device is disclosed in US 6 135 356 A .
  • Oscillating sprinklers are a popular choice for residential (e.g., home lawns) and commercial (e.g., golf courses) uses.
  • the oscillating sprinkler is inserted or rested upon a ground surface, coupled to a fluid source, and activated to provide a stream of fluid in an oscillating manner about an axis of rotation.
  • the oscillating sprinkler typically includes a plurality of jets or nozzles arranged axially or substantially axially along a body of the oscillating sprinkler. As such, as the body rotates about the axis, the jets also rotate about the axis.
  • a "width" control knob is typically included with the oscillating sprinkler.
  • the width control knob enables a user to adjust an angle of emission of the fluid from the plurality of jets: a large angle corresponds with a greater coverage area than a small angle. While such a knob is beneficial in tailoring the emitted fluid to the intended area, the placement of the width control knob is typically in an inconvenient/cumbersome location for the user especially when the sprinkler is in use.
  • the present invention relates to a sprinkler according to independent claim 1.
  • the sprinkler includes a body defining a fluid passage; a frame coupled to the body, the frame disposed in an internal volume of the body proximate the fluid passage, wherein the frame defines a plurality of apertures; a first toggle movably coupled to the body; a first slider disposed within the internal volume of the body and coupled to the first toggle, the first slider defining a plurality of apertures; and, a first plurality of jets coupled to the frame, wherein each jet in the first plurality of jets is received by an aperture of each of the first slider and the frame, and wherein fluid from the fluid passage is selectively provided to the first plurality of jets.
  • the first toggle is movable between a first position and a second position, wherein movement of the first toggle to the second position moves the first slider in a same direction as the first toggle, wherein the movement of the first slider in the same direction causes the first slider to move at least one jet in the first plurality of jets in the same direction such that the at least one jet moves in the same direction as the first toggle.
  • an irrigation device with an intuitive width control mechanism is shown herein.
  • the irrigation device is configured as an oscillating sprinkler that includes the intuitive width control mechanism.
  • the oscillating sprinkler includes a body, a first plurality of jets, a second plurality of jets, a first slider cooperating with the first plurality of jets, a second slider cooperating with the second plurality of jets, a first toggle coupled to the first slider, and among other components a second toggle coupled to the second slider.
  • the body is rotatable about a longitudinal axis to provide the oscillation feature of the oscillating sprinkler.
  • the first and second pluralities of jets are resiliently flexibly and configured to emit a fluid (e.g., water) when the sprinkler is in use.
  • the first and second toggles are coupled to the body and, according to the present disclosure, are rotatable about an axis that is perpendicular or substantially perpendicular to the axis of rotation of the body.
  • the first and second toggles are positioned along or substantially along the axis of rotation of the body.
  • rotation of the first and second toggles moves the first and second sliders, respectively. Movement of the first and second sliders impacts at least one of the jets in the first and second pluralities of jets, respectively, to push the at least one of the jets in the first and second pluralities of jets.
  • the at least one jet in the first and second pluralities of jets is angularly bent.
  • the angular movement of the at least one jet in the first and second pluralities of jets respectively, adjusts a width of dispersal of the emitted fluid (hence, a "width" control mechanism) from the sprinkler.
  • the width control mechanism may enable a user to control the coverage area of the emitted fluid from the oscillating sprinkler to correspond with or substantially correspond with a desired coverage area (i.e., an area desired to be wetted).
  • the first toggle cooperates with the first plurality of jets while the second toggle cooperates with the second plurality of jets such that each plurality of jets is independently adjustable.
  • a user may rotate the first toggle to provide a wide or large jet angle for the first plurality of jets while adjusting the second toggle provide a narrow or small jet angle for the second plurality of jets.
  • such tailoring may enable the user to better control the coverage area as compared to conventional oscillating sprinklers.
  • the angle of rotation of the toggle substantially corresponds with the angle of at least one of the jets. As such, a user can observe the anticipated fluid dispersal angle without having to turn the fluid on/off to gain an indication. Therefore, a time-savings and convenience benefit may be realized.
  • the type of fluid may be highly configurable.
  • the type of fluid may be water, which may be provided by a spigot or other water source.
  • a reservoir containing a mixture of water and fertilizer may be used by the sprinkler.
  • a variety of other types of fluids may be used.
  • the irrigation device of the present disclosure may provide water in addition to various other types of fluids.
  • an irrigation device shown as an oscillating sprinkler 100
  • the oscillating sprinkler 100 is configured to emit fluid to wet or substantially wet a desired area.
  • the oscillating sprinkler 100 includes a base 101 coupled to a body 110, an end cap 111, a fluid inlet 112, a pair of toggles shown as a first toggle 180a and a second toggle 180b, a plurality of jets 141 coupled to the body 110 and split into a first plurality of jets 143 and a second plurality of jets 144, and various other components described herein below.
  • the body 110 rotates about an axis 200 (hence, an "oscillating" sprinkler).
  • the plurality of jets 141 is substantially aligned with the axis 200.
  • the axis 200 corresponds with an alignment axis for the plurality of jets 141 and the toggles 180a, 180b, where the plurality of jets 141 and toggles 180a, 180b are aligned with that axis in a straight or substantially straight line.
  • the jets 141 and toggles 180a, 180b may be disposed differently than shown and described (e.g., a random pattern, not aligned in a substantially straight line, etc.).
  • this straight line arrangement between the toggles 180a, 180b and the jets 141 may aid a user in visualizing the movement of the jets 141 as one or more of the toggles 180a and 180b are rotated, moved, or otherwise actuated.
  • Fluid provided via the fluid inlet 112 to the plurality of jets 141 is emitted about the axis 200 as the body 110 rotates about the axis 200.
  • any type of drive mechanism to cause rotation of the body 110 (or a portion thereof) about the axis 200 may be used with sprinkler 100.
  • a motor such as an electric motor may be used.
  • a fluid-driven rotation mechanism shown as a turbine or water wheel 113, may be utilized to drive the body 110 about the axis 200. As fluid impacts the water wheel 113, the water wheel 113 is driven to, in turn, cause rotation of the body 110.
  • this drive mechanism may be one or more speed control mechanisms (e.g., gear trains) to control the rotational speed of the body 110 about the axis 200 independent of the fluid pressure provided to the sprinkler 100 via the fluid inlet 112.
  • the base 101 may be structured to support the body 110 above a support surface (e.g., ground surface).
  • a support surface e.g., ground surface
  • the base 101 is shown to be configured as a rest-type base where the base 101 rests upon a support surface.
  • the base 101 may be configured as an insertable-type base (e.g., spike) that facilitates and enables insertion of the base 101 into the support surface. This configuration may be desired to substantially securely hold the base 101 (and, in turn, the oscillating sprinkler 100) in a desired location. It should be understood that many coupling devices or mechanisms may be used to couple the body 110 to the base 101.
  • the body 110 may simply rest in an opening or snap into an opening of the base 101 to suspend the body 110 above or substantially above the support surface.
  • the base 101 may be of integral construction with, for example, the fluid inlet 112 and the end cap 111.
  • the body 110 or housing is shown as a substantially hollow tube structured to support and couple to many of the components described herein.
  • the body 110 has a cylindrical shape where the axis 200 is aligned or substantially aligned with the longitudinal axis of the body 110.
  • the body 110 defines a circular or substantially circular cross-section.
  • the plurality of jets 141 is provided on a curved surface of the body 110. Additional features of the body 110 are described herein below with respect to FIG. 3 .
  • the fluid inlet 112 is structured to permit and enable coupling of the sprinkler 100 to a fluid source (e.g., a hose connected to a spigot or other fluid source). As such, the fluid inlet 112 defines a fluid entry point for the sprinkler 100. In one embodiment (see FIGS. 3-4 ), the fluid inlet 112 may define/include a plurality of threads that are rotatably engageable with a complementary plurality of threads on the fluid source. In another embodiment, any type of fluid connection/coupling mechanism or device may be used (e.g., a quick-connect feature, a snap engagement, etc.).

  • FIG. 3 depicts a side cross-sectional view of the sprinkler 100 with the base 101 removed and the plurality of jets 141 in a narrow or starting position
  • FIG. 4 depicts a close-up view of section 4-4 from FIG. 3
  • FIG. 5 depicts a side cross-sectional view of the sprinkler 100 with the base 101 removed and the plurality of jets 141 in an end or wide position.
  • the jets 141 may be described herein to be movable from a starting (or narrow) position to an end (or wide) position.
  • the terms “narrow” and “wide” refer to the fluid dispersal coverage area.
  • the jets 141 In the wide position, the jets 141 (or at least some of the plurality of jets) are angled outward and away from the body 110.
  • the jets 141 In the narrow position, the jets 141 (or at least some of the plurality of jets) are positioned in a substantially upright position (i.e., parallel to the vertical plane 220).

  • each component in the pair of nozzle bend controllers 150a and 150b, bottom sliders 160a and 160b, top sliders 170a and 170b, and toggles 180a and 180b are identical in structure to each other.
  • the body 110 includes a bottom part 120 (e.g., section, housing, portion, etc.) and a top part 130.
  • the body 110 may be constructed (at least partly) from by two parts.
  • the bottom part 120 includes a frame 121 that defines a plurality of apertures 122 (e.g., openings, holes, etc.) and a fluid passage 123 (e.g., channel, etc.) defined by the body 110.
  • the fluid passage 123 is fluidly coupled to the fluid inlet 112, such that fluid may be provided from the inlet 112 to the passage 123 and, eventually, the jets 141.

  • the fluid passage 123 may have any shape and size desired by the designer. In the example shown, the fluid passage 123 corresponds with a circular or substantially circular cross-sectional shape. Of course, in other embodiments, any shape and size may be used.
  • the frame 121 (e.g., rail, etc.) is disposed on a top or upper part of the fluid passage 123 (based on the viewpoint in FIG. 3 ).
  • the frame 121 is a predominately flat component of unitary construction.

  • a pair of openings 131 e.g., apertures, voids, etc.
  • apertures 132 e.g., holes
  • Coupling of the upper part 130 to the lower part 120 may be via any type of coupling mechanism including, but not limited to, a snap engagement, one or more fasteners (e.g., screws, pins, etc.), an adhesive (e.g., glue), an interference type relationship, etc.
  • the openings 132 have a slot or oval type shape, where the length of the slot (i.e., the long portion) is oriented along the axis 200.
  • each jet 141 is configured to extend through each opening 132 (i.e., one jet per opening).

  • one or more fasteners may be used.
  • coupling between the frame 121 and the jet rail 140 may be performed in a fluid tight manner or substantially a fluid tight manner.
  • fluid provided to the passage 123 can only be directed through each of the pluralities of jets 141 as opposed to a space or crevice between the jet rail 140 and the frame 121. Beneficially, such a feature avoids leaks there-between.
  • the jets 141 and body 142 are of integral construction (e.g., a one-piece component).

  • each bend structure 153a is disposed proximate to a base of the jet 141 (i.e., closer to the frame 121 than to the upper part 130).
  • the bend structure 153a may provide a counter force to a force applied by the top slider 170a to an upper part of the jet 141 to, in turn, enable only substantially the upper part of the jet 141 to bend/move into a desired angle of fluid emission. It should be understood that the precise structure of the bend structure 153a is highly configurable.
  • the bend/flexion/angular movement of the jet 141 is also highly configurable.

Further and similar to the jet bend controllers 150a and 150b and the upper sliders 170a and 170b, in other configurations, only one bottom slider may be used. Such a configuration may be used with only one toggle and for a relatively shorter longitudinal length sprinkler 100 than that depicted in Figures.

In particular, the sliders 170a and 160a slide or translate towards the fluid inlet section 112 (i.e., the sliders 170a and 160a move in a direction corresponding to the rotation direction of the toggle 180a).
  • the jet bend controller 150a provides a stationary surface for the jets 141 to engage with and, in turn, bend upon (particularly, the bend structure 153a).

  • the remaining second through eighth jets 141 are disposed at a constant decreasing angle relative to the vertical plane 220 in this example.
  • the first through eighth jets 141 have a constant angle of separation between each successive jet 141 (i.e., the third jet is at an approximate 33.75 degree angle while the second jet is at an approximate 39.38 degree angle and the fourth jet is at an approximate 28.13 degree angle, which corresponds with a decreasing amount of 5.68 degrees between each jet going from the first to the eighth and ninth jets).
  • this linear relationship between the jets may be replaced by a different desired relationship or none at all.
  • a user may desire to decrease the width of coverage of the sprinkler 100 and move the jets 141 back to the starting position (i.e., FIG. 3 ).
  • the user may grab the tab 182a and move or rotate the toggle 180a clockwise (based on the view in FIG. 5 )(i.e., towards the end cap 111). Due to the coupling with the top slider 170a and the bottom slider 160a, movement of the toggle 180a causes, forces, or otherwise pushes the sliders 170a and 160a to move (and, in particular, slide or translate) away from the fluid inlet 112 and towards the end cap 111.
  • the body 171a that defines the apertures 172a impacts, contacts, or engages with the jet 141 to push the jet 141 away from the toggle 180a.

  • the bottom slider 160a pushes the fifth, sixth, seventh, and eighth jets 141 before the top slider 170a contacts those jets to push them away from the toggle 180a.
  • the rotational movement of the toggle 180a towards the other toggle 180b (or end cap 111, or towards the jets 141) functions to straighten the jets 141 (i.e., move them back towards the starting position, which is in an orientation that is parallel or substantially parallel to the vertical plane 220).
  • the position of the toggle 180a (particularly, the tab 182a) then matches or substantially matches the position of the first jet 141 (i.e., jet closest to the toggle 180a).
  • the tab 182a and the first jet 141 are oriented in a manner that is substantially upright/parallel to the vertical plane 220.
  • Applicant has determined that the jet 141 angles at the end (e.g., fifth through eighth jets) are slightly bent (i.e., approximately two (2) degrees relative to the vertical plane) rather than being completely upright. That being said, in other embodiments, more or less bend may be implemented with some or all of the jets in the narrow position.
  • the user may control the width of the fluid stream dispersed from the oscillating sprinkler 100.
  • the toggle 180a may be moved to various intermediate positions between the narrow and wide positions as well.

  • various colors may be provided on the top slider, such that as the top slider is moved a different color may be visible (e.g., through the openings 132 of the top part 130).
  • colors may have different meanings such that a different color indicates a different change in amplitude.
  • colors may be used with another component of the sprinkler 100 to show the change in amplitude of the nozzle angle during adjustment by the toggle.

Further, these components may be constructed from any suitable material including, but not limited to, a plastic material, rubber, a metal or metal alloy material, and/or any combination therewith. For example, the use of engineered plastics may provide a preferred combination of light weight and strength. According to other embodiments, a number of alternate materials can be used to produce the sprinkler: cast or machined aluminum or brass could be utilized in the construction, a variety of steels, various composites, and/or any combination thereof. Thus, those of ordinary skill in the art will appreciate the high configurability of the components.
  • the term “coupled” or other similar terms, such as “attached,” means the joining of two members directly or indirectly to one another. Such joining may be achieved directly with the two members or the two members and any additional intermediate members being attached to one another and the two members.
